2) broadband pulsed laser beam
宽频带脉冲光束
1.
The nonlinear hot image effect of high-power broadband pulsed laser beam has been investigated theoretically and numerically.
同时对宽频带"热像"的形成过程给出了解释,指出宽频带脉冲光束"热像"的形成类似于时间分片的连续单色光"热像"形成过程。
3) broadband pulse
宽带脉冲
1.
It is found that they are the same in the neighbourhood of z-axis for narrowband pulses, but in the case of broadband pulses, singularities emerge near z-axis for pulsed beams obtained by using complex amplitude envelope representation and only complex ana.
数值结果表明脉冲光束为窄带时,在传输方向轴中心的一定范围内两种解是一致的,而对于宽带脉冲光束,复振幅包络解在轴中心较近的距离即表现出奇异性,复解析信号解才是符合物理意义的表示式。
4) pulse bandwidth
脉冲带宽

从傍轴波动方程出发,给出了超短双曲正割脉冲光束的解析解。
3.
By using slowly-varying envelope approximation, a family of solutions of the paraxial wave equation are found in theory, which represents a new family of ultrashort pulsed beams called ultrashort pulsed complex argument Sinc-Gaussian beams.
利用理论解析推导的方法,在傍轴近似条件下,给出了一组新的超短脉冲光束的解析解,称为超短脉冲复宗量辛格高斯光束。
补充资料：宽带和窄带业务
宽带业务是相对窄带业务而言的，一般来说，对于速率低于2Mb/s的通信业务统称窄带业务，如电话网、N-ISDN所提供的业务。对于高于2Mb/s的通信业务，如帧中继业务、视频点播、ATM业务、TV会议等称为宽带通信业务。 目前投入应用的宽带接入技术主要有两种：ADSL和FTTX＋LAN。
